Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

CEN12CA038
The pilot reported that the motor-glider encountered a wind gust during the landing flare that resulted in a 15-degree runway misalignment. The pilot considered a go-around, but chose to attempt a landing in the grass adjacent to the runway because he believed that was the safest course of action. He stated that another wind gust "caught" the right wing and the motor-glider ground looped in the grass, nosed over, and sustained substantial damage to the fuselage. The pilot reported that the wind at the time of the accident was gusting to 25 knots. The pilot reported no mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Full Narrative
The pilot reported that the motor-glider encountered a wind gust during the landing flare that resulted in a 15-degree runway misalignment. The pilot considered a go-around, but elected to attempt a landing in the grass adjacent to the runway as the safest course of action. He stated that another wind gust "caught" the right wing and the motor-glider ground looped in the grass. The motor-glider subsequently nosed over and received substantial damage to its fuselage. The pilot reported no mechanical malfunctions or failures. A weather reporting station near the accident airport recorded the wind speed as 15 knots gusting to 25 knots. The reported wind direction was aligned with the runway direction.
